Here is a Pure Data (PD) patch I have been working on entitled 'Filth Box'. It is a distortion patch which can be used from audio coming from your laptop microphone, external microphone and I have also included a synthesiser you can connect a midi controller to and draw in the waveform it generates!

I have had great fun using this; I hope you all do too!

Any feedback will be appreciated and I may upload updated versions of the patch and samples of audio it has generated later, so keep checking the page!
